I am taking a hard look at picking up a 2013 x-30 (essentially new, less than 15 hours), but the boat is outfitted with the 5.7 liter engine. Or current boat is a 07 X-2 with the MCX, and the only reason for the move would be for greater space and a better surf wake. My wife and I are beginner surfers (until this summer, we spent most time slaloming and boarding). The dealer has recommended adding 750lb/side of additional rear ballast to go along with the stock ballast.

Thoughts on the 5.7 (vs. ordering a 2014 with the 6.0) given the above setup and intended use would be greatly appreciated!
